=not here shown, and carry theeb over .a suitable supporting device, such {as a bed- ;p'late 5, and deliverg-the, same to cutting mechanismaG. The ifieeding rollers in this particular ,form of feeding mechanism are driven intermittently;- and to this end the feedingzroll'er 2 has loosely zIHOLlIitB'Cl on its shaft .7 a gear .S fto which [is rigidly secured a ratchet heel 9 adapted to cooperate With a pawl 10 carried by a disk 11 rigidly secured to the shaft. This clutch-connection causes ithe shaft to be rotated only when the gear Sismoved in one d-irection. Movement :is imparted to the gear by a segmental rack 12 pivotally mounted at 13 .on the trainer 1 and havihg a longitudinal slot-:14 inwhich is mounted a slide block l5 having' journaled therein a :wrist gpin.l6. which, in turn, is mounted upon a disk 17. ;The wrist .pin jis preferably adjustable ,on the, disk to enable the amount of movement of the segment to be regulated Thisis accomplished by mounting it inga transverse slotor groove 18. This particular type of {feeding inechanisin, illQWQVGI, does not form a .partpf the present inveution'fhut lis ,lshown fdescrihed and .,claimedin .an application ra patent filed nie Feb.=.9,-1914,BerQNO. 11,567. The disk may be actuated in any, suitable manner. I

,the, presentlinstance I have shoi vn the saine mounted on. shes 19 journaled in the side l me nhers or frame 1 and .havi-ngsecured thereto a sprocket Wheel "20 means a of which it as jopejratiyel conn cted with a moyingx part or empress; "The (jetting inechanisin;'6 is actuated by means of ccn- "are imme- "Tr ss" pen-S1 are or the Qrdim ry imrarmngemesti "Extendi g 1 1w the pens lea stsirxafifd e oothe t s t mei a 29; which e'xtqaasi into supply eceptacle 30 and feeds the ink to the pens. The pens are adapted to engage the paper intermittently, the length of time which they remain in engagement with the paper and, consequently, the length of the line, being adjustable, To control the operative engagement of the pens with the paper I have provided an actuating device which iscontrolled by a movable part of the printing press and preferably is directly connectedwith the feeding mechanism. In the present instance, the shaft 28, which is a rock shaft, has loosely mounted thereon an arm, or lever, 31 which projects both to the-front and to the rear of the shaft. Rigidly secured to the shaft and also projecting from the front and rear thereof is a second arm or lever 32. I To cause these parts to move in unison I have mounted in the upper arm, on opposite sides of the shaft 28, screws 33 which engage the adjacent portions of the lever 31 and thus form a rigid but adjustable connection between this lever and the lever 32. The forward portion of the upper lever 32 is also provided with a second screw 34: adapted to engage a plate 35 carried by the frame 1 and limit the downward movement of the lever 32 and, consequently, limit the pressure with which the pens are held in engagement with the paper. 1 Any suitable means may be providedrfor moving the pens toward the paper but, in the present construction, the weight of the longer ends of the lever and the parts carried thereby is ample forthis purpose and will serve to hold the. pens normallyiin engagement with the paper. To move the pens out of engagement with the paper I provide a trip lever and a cam. The trip lever is here shown at 36, is pivotally mounted on the frame 1 and has two arms, one of which is upturned as shown at 37, to engage the lever 31, one end of the lever being turned down, as shown at 38, to facilitate this contact. The second arm 39 of thelever 36 is arranged to be engaged by the periphery of a cam 40. The engagement of the cam with the arm of the leverwill raise the pens out of contact with the paper and retain thesame out of such contactuntil the raised portion of the cam has passed the trip-lever, and the length of, the lines will correspond to the distances between the raised portion and the pens.- In order that the length of the lines may be varied I have provideda cam 40 witha disklikebody: portion 41 having therein two grooves 42 in which are mounted a plurality of segmental cam plates 43. The body portion a1 is provided with a series of holes 14 to receive bolts 45 which extend through the cam plates 43and by means .of .which theseplatesmay be secured adj usted positions.

= have shown and one embodiment of my invention it will be understood that this has been chosen for the purpose of illustration only, and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, 'is:

1. In a printing press, the combination with a frame, a paper supporting device carried by said frame, and mechanism mounted on said frame to feed a web of paper through said press and over said supporting device, of a ruling device comprising a rock shaft mounted on said frame, pens mounted on said shaft above said supporting device, and adapted to be moved into and out of contact with' the paper thereon by the move ment of said shaft, an arm rigidly secured to said shaft, a secondarm loosely mounted on said shaft, means for retaining said arms in adjusted positions relatively one too the other and forlimiting the movement of said shaft in one direction, a trip lever pivotally mounted on said frame and arranged to engage one of said arms, and a cam connected with said feeding mechanism and having adjustable cam surfaces to engage said trip lever and actuate said rock shaft.

2. In a printing press, the combination, with a frame, feeding rollers mounted in said frame, actuating mechanism for onev of said feedingrollers. mounted on said frame and comprising'a shaft, of a second shaft mounted on said frame, a series of ruling pens carried by said second shaft, an arm loosely mounted on said shaft, a second arm rigidly secured to said second shaft, set

screws extending through said second arm on opposite sides of said; second shaftand engagingcorresponding portions of said first arm, means to limit the movement of said second arm, a trip lever pivotally mounted carried thereby, an armloosely mounted on saidsh-aft, a second arm rigidly secured to sa1dshaft,means;for retaining said arms in adjusted positionsrelatively one to the other and for limiting the movementof said shaft in one direction, a trip lever arranged toengage one of said arms, and a cam arsaid shaft.
